1. Points for Handling
Follow this manual and precautions when handling the inverter. Incorrect
handling could lead to inhibited operation or a drop operating life. In the worst
case, the inverter could be damaged.
Power supply Use within + 10%, -15% of the tolerable input
voltage range, and with in±5% of the tolerable
input frequency range.
Circuit breaker
（MCCB）Size a breaker from the selection table on
page 21.
Magnet contactor
（MC）
A magnetic contactor is not required in normal
use. If installed, do not start or stop the inverter
with the magnet contactor.
Power factor
improvement
reactor
Connect this when the power factor must be
improved.
Inverter
The ambient temperature is the most important
factor for the installation site.
Make sure that the tolerable value is not
exceeded. (See page 12)
Thermal relay
for open phase
protection
The thermal relay built into the inverter is used
to protect against overloads.
Use an open phase protection thermal relay
for open phase protection.
Motor 3-phase induction motor

Because the life of the inverter is greatly affected by ambient temperature, use it within
tolerable temperature range.
Also, pay attention to the installation directions and conditions. (See page 12)
◆Use the inverter only within tolerable ambient temperature range.(-10 to +50℃)
Applying power voltage to the output terminal U, V or W will damage the inverter.
Check carefully for fault wiring and operation sequence (commercial changeover circuit, etc.).
Never apply a voltage that exceeds the tolerable voltage of the inverter.
◆The inverter will be damaged if the power voltage is applied to its output terminal.
This is extremely dangerous the inverter contains high-voltage circuit. Be sure to wait at
least 5 minutes after the inverter power has been turned OFF, before making an internal
check. Do not touch the heat sink fins or brake resistor during operation as these parts
will become hot during operation.
◆Never touch the inside of the inverter during operation.
The main circuit of the inverter contains a higher harmonic component and may interfere
with communications equipment such as AM radios if these are used nearby. The amount
of radio interference depends on the field strength in the area where the inverter is used.
While it is difficult to completely eliminate radio interference, it may be reduced by changing
the angle of your radio antenna, using a noise filter with the inverter, housing the inverter in
a metallic shield box, or routing inverter cables in metal conduit. (Please inquire separately.)
◆Radio interference
To measure the insulation resistance of the power supply cables or the motor cables,
them from the inverter. Never conduct insulation testing on the control circuits. However,
insulation testing can be performed between the charging unit and the ground.
◆Do not attempt insulation testing between the inverter cables.
Switching the inverter on the power supply side ON and OFF frequently by a magnetic
contactor, can cause the inverter to malfunction. Do not turn the inverter on the load side
ON and OFF during operation as this causes inverter fault trips. Start or stop the motor
only by means of inverter run signals.
◆If a magnetic contactor is connected to the power supply side or the load side
of the inverter, never use it to start or stop the motor (inverter).
Such devices can damage the inverter, its capacitors and other parts. Remove the device
if one is connected.
◆Do not connect a power factor capacitor or suppressor to the output terminal
of the inverter.
◆Do not use the inverter for loads other than a motor or for single-phase motors.
◆If parameters are frequently written in, lifetime of non-volatile memory (EEPROM)
will be shorten.
The maximum writing times of non-volatile memory (EEPROM) used in
VF100 is 100,000 times. Therefore, do not write the parameters frequently.
2. Special Precautions
10

Various protection functions such as stall prevention, current limiting and overcurrent
shut-off are built in the inverter.
These protection functions are used to protect the inverter from the sudden abnormal
conditions in use, so they are not the control functions to be always used.
Therefore, do not use the applications in which those protection functions activate
in the normal operating conditions.
In some cases, the inverter's life may be shorten, or the inverter may be damaged.
Always measure the output current, etc. with a measuring instrument, and check the
details of the fault trip memory, and confirm that there is no problem in the conditions
for all the precautions and specifications described in the manual when using the inverter.
◆Precautions regarding inverter's protection function
11

Install the inverter on a non-combustible material such as metal.
Installing it on other material could lead to fire.
Do not place the inverter near flammable materials.
Failure to do so could lead to fire.
Do not hold the terminal cover during transportation.
Failure to do so could cause the inverter to drop and lead to injuries.
Do not allow foreign matter such as metal swarf enter the unit.
Entry of this type of matter could lead to fire.
Mount the inverter according to the instruction manual in a place where the
weight can be withstood.
Failure to do so could lead to dropping of the inverter and to injuries.
Do not install or operate an inverter that is damaged or with parts missing.
Failure to do so could lead to injury.
。
[Install the inverter vertically]
・Areas subject to direct sunlight
・Areas where rain water, water drops or
oil drops may come in contact.
・Areas subject to vibration.
Installing the inverter in any other way
decreases its heat dissipation effect and
results in malfunction.
[Avoid installing the inverter in the
following locations]
・Areas subject to water or high levels of
humidity.
・Areas with large amounts of oil mist, dust
or fiber dust.
・Areas where corrosive gases, explosive
gases or flammable gases are present.
・Installation onto flammable materials such
as wood, or near flammable materials.
Vertical Horizontal Sideways
[Make sure the ambient temperature stays
within the specifications]
The ambient temperature surrounding the
inverter will increase when it is installed near
a heating unit or housed inside a panel.
This may reduce the lift of the inverter. If you
want to house the inverter inside a panel,
give careful consideration to the cooling
method and panel size.
Tolerable ambient temperature: -10 to 50℃
(Ambient temperatures should be measured
at a point 5cm from the inverter.)
If more than one inverters are tightly installed
in horizontal direction, tolerable
ambient temperature should be -10 to + 40℃.
